Both Christina Hendricks and Olivia Munn have allegedly had their phones hacked, with several naked pictures of the two actresses hitting the internet. But Hendricks and Munn aren't the first celebrities to face off against hackers. From Scarlett Johannson to Jessica Alba, here are seven more stars whose naked pictures have been leaked online by hackers. Photo: Reuters

Rumors that Scarlett Johannson's phone had been hacked first emerged in March 2011, but it wasn't until September that Hollywood Leaks, a hacker ring believed to be behind 50 or more celebrity hackings, leaked nude photos of the actress online. Johannson, who shot the photos for then-husband Ryan Reynolds, shrugged off the leak: "I know my best angles." Photo: Reuters

Kunis and Timberlake were rumored to have been dating even since the pair starred together in "Friends With Benefits." It was when Kunis's cell phone was hacked, however, that those rumors really began to catch fire. Along with a shot of the actress in a bathtub, there was also a leaked photo of Timberlake shirtless and wearing a pink underwear on his head. Both the actors' reps denied that the two were involved, and claimed the photos had nothing to do with one another. Photo: Reuters

Paris Hilton doesn't need a hacker for naked pictures of her to show up on the Internet, but in 2005, a Massachusetts teen did break into her T-Mobile Sidekick, posting her entire contact list, including the phone numbers and email addresses of several high-profile celebrities, online. The kid was eventually caught, and got 11 months detention in a juvenile facility for his pains. Photo: Reuters

Lively's reps have maintained that leaked photos allegedly of the "Gossip Girl" star are in fact of some other girl. A hacker claiming responsibility for the initial leak had this to say in response: "Oh, yes, Blake's rep. These are totally fake. We really, really believe you. Want moar?" More naked photos soon followed. Photo: Reuters

It's unclear how many photos of Cyrus are due to hackers and how many are simply leaks from people the singer and actress shouldn't have trusted. Regardless, the former Disney princess now has several infamous shots of underwear poses and wet T-shirts to her name. Photo: Reuters

Racy pictures of the "Voice" coach wearing little more than a couple strips of fabric and some pasties hit the Internet thanks what the singer's rep claimed was a hacker who stole them from her stylist. Some, however, believed that either the stylist or Aguilera herself had them released to renew interest in the star's career. Photo: Reuters

Photos of a topless, newly pregnant Alba were leaked online two year ago, and sites like Celebrity Jihad quickly picked them up. Because the photos features tender scenes like husband Cash Warren kissing her and the actress stroking her growing belly, these pictures are assumed to be authentic, not fake. Photo: Reuters

Hendricks' rep has admitted that while the voluptuous woman baring her breasts in one photo was not Hendricks, the rest were in fact pictures taken from the star's phone.

She doesn't know who hacked her phone -- but the proper authorities have been notified and an investigation is underway, the rep was quoted as saying by TMZ.

Photos of Olivia Munn in a bra and bikini, meanwhile, were apparently taken from the actress's Twitter and blog. Shots of a naked woman hackers claim to be Munn, however, are said to be fake. Munn herself commented on the leaked photos with a Twitter post, tweeting, If you ever hacked my phone, these are the pictures you'd find and linking to pictures of a baby and a cat.

Christina Hendricks and Olivia Munn aren't the first actresses to have leaked photos attributed to them, and Hendricks is certainly not the first to get her phone hacked.
